I have never been one to mess with fin settings, learning the course I took the wing off and put it back on when I started getting consistent into 32 -15. The skiers at my club seem to know ALOT about fin settings and I want to get the basics so I can at least be a bit more knowledgeable. Without a novel can someone help explain terms like: Long, Shallow, Wing Angle and what changes do what to how the ski reacts?
